Makeover Monday | Week 8 | 2019: Which States produce the most wind energy?

Posted by

This week we look at how much wind energy is produced in different US states. The original viz (and awfully opinionated, anti-wind energy article) comes from

What works well:

  • States are sorted in descending order from highest to lowest installed capacity
  • The title is short and captivating (even if a little vague)
  • Adding the total investment figures below each state adds further context

What could be improved:

  • The y-axis: the distance from 100 to 1,000 is as large as that from 10,000 to 20,000. That makes no sense, especially when the visualization is essentially a gimmicky bar chart that starts at zero
  • Equally, the color suggests grouping into bands of unequal sizes
  • The labelling is not aligned consistently with gaps on the x-axis becoming much smaller from left to right
  • The labels at the far right are essentially illegible
  • The icons are so unnecessary and cover much of the chart area without adding much value. A simple bar chart would have been a much better choice

What I focused on:

  • I was keen to build another dashboard with BANs and to keep the viz itself quite simple
  • I initially planned to include a scatterplot showing investment vs output but all states are pretty much on a straight line, so there is nothing particularly interesting to see there.
  • I ended up with this:
